working with dark images

Hi,
If I have a camera sitting in a dark area, is there anyway that I can get better (less noisy) images?
Let's say that I have a surveillance camera capturing frames at night in a parking lot, how can I get rid of some of the noises?

Thanks,
--Rudy

I think you can try the noise filtering functions -median or -morphology , check this http://www.imagemagick.org/Usage/morphology/#basic
